  • What does interpolation in an optical power meter mean

    What does interpolation in an optical power meter mean

    This is not normally an issue, since the test wavelength is usually known, but has some drawbacks. Firstly, the user must set the meter to the correct test wavelength, and secondly, the presence of spurious wavelengths can result in wrong readings.OverviewAn optical power meter (OPM) is a device used to measure the power in an signal. The term usually refers to a device. The major types are (Si), (Ge) and (InGaAs). Additionally, these may be used with attenuating elements for high optical power testing, or wavelengt. A typical OPM is linear from about 0 dBm (1 milli Watt) to about -50 dBm (10 nano Watt), although the display range may be larger.
